That site certainly looks very good, but is awfully slow. I'd have prefered a not so flashy design, and I also think this would have presented the police department better. It does look modern and slick, but not very professional/official. Makes sense if they want to present themselves as modern, but it's not really accessible. I visit official sites like that to inform myself, so the best design would've been clear, performant (in case someone has an old PC) and, in the optimal case, include a contact form/chat applet.
It's a well designed website, but the design doesn't fit the target group.
